The market's preference for the model of "sampling on the high-voltage side and mitigation on the low-voltage side" is not accidental. It is the optimal solution determined by a combination of factors including technical feasibility, economic efficiency, safety, and mitigation effectiveness. The logic behind this can be understood with a simple analogy: A doctor performs a "blood te...
EMC (Electromagnetic Compatibility) testing for an Active Harmonic Filter AHF is critical and non-negotiable. An AHF(APF) is a power electronics device (like a high-frequency inverter) that injects canceling currents into a noisy electrical system. If poorly designed, it can become a significant source of electromagnetic interference (EMI) itself, disrupting other equipment. Conversely, it mu...
